I'm trying to generate a graph using SNMP of actual memory used on a
Linux system running Net-SNMP. In theory:
memTotalReal.0 - memBuffer.0 - memCached.0 - memAvailReal.0
Is the real memory available.
I would like to graph this and also memTotalReal.0. I am having a hard
time figuring out the right way to do this however... I am currently
using:
Target[memory_used]: memTotalReal.0&memTotalReal.0:[EMAIL PROTECTED] -
memBuffer.0&memIndex.0:[EMAIL PROTECTED] -
memCached.0&memIndex.0:[EMAIL PROTECTED] -
memAvailReal.0&memIndex.0:[EMAIL PROTECTED]
(Pardon the word wrapping). memIndex.0 evaluates to 0 so that my
second variable doesn't continue to get subtracted.
Is there a better way to do this? I tried doing something like:
memTotalReal.0&memTotalReal.0:<stuff> - memBuffer.0&0:<stuff> ....
But this doesn't evaluate. Other than the first group, I just want the
second half of the & statement to be 0.
TIA,
Ray
